Fig. 17 is a sectional View, the section bef ing taken on line 17-l7 of Fig. 16. Fig. 1 8 illustrates a. method of 'reinforcing the side and cent-er section connection by extending 'flanges 2 of the side section extensions l and flanges i201E the center section jews 9 securing said flanges together by rivets 3G. Fig. 19 is a View similar to F ig. 18 with the cover plate of: Figs. l7inclusive and the flanges, etc.. of Fig: 18 combined in one struc-ture.

The object. of the invention is to providelirst, a sectional bolste: in which all of the parte may lie readily assembled to forni a bolster structure complete in itself :is en article ot' manufacture. :ind which is also capable oft being assembled with the underlr'ainc ol" a car as shown in the drawings; stc'nd, to .so connect the parts ot' the bolsier as to develog in a simple and. ellicient manner the full strength of the engaging parts so that the bolster will perform its full function as o supporting member independently ot" its association with other meer bers of a car underfranie in which Ait may he used.

Referiinnnu'n'e particularly to the dran-in ings` A and l are bolster sections of cest metal arrangcdon opposite sides of spaced channel-slniiied center sills and provided each n'ithnn extension i arranged to lie in n plane a little to 'one side oi' the central longitudinal pllme ol the body oi each of the two bolster sections, and when said sections are in place each extension thus offset occnpies a position alongside ol the extension. ,on the opposed section. ein of each extension l and for a pnrtn its length each extension is provided with u flange :2 designed to i'ciniiiirce that port. The .sections are further provided with nailinn siii chair-sas at .'35 and i, seat 5 for the side siii member of the under'fraine, t side bering; 5, sind :i :coping stnple 7, which Along the upper man Clt also answers the purpose of a jacking casting. The overlapping extensions 1 of the bolster' side sections are arranged to lie within the recess 8 of: the spaced jaws 9 rising from the center section C of the bolster, best known in the car art as the bolster center casting, which is provided with an integral center bearing portion 10. The jaws 9 are provided with holes 9 which register with the holes 1a in extensions 1 through which are passed rivets or other fastening means 11. Such construction provides a rigid connection Yfor the bolster parts, enabling the assembled structure to act as a unit in resisting service stresses. To lend further rigidity to the engaging parts 1 and 9, the jawsl 9 may be provided at their upper edges with outwardly projecting horizontal flanges 12 which terminate in vertical flanges 13 for connecting the center sill 14 and flanges 15 of the side sections. To further insure the proper spacing of the opposed side sections when they are to be used in an underframe in which the center sills are continuous through the bolster, as shown herein, they are each provided at their inner lower portions with shouldered recesses v16 adapted to receive the Bauges 17 of the center section C, which flanges 17 assist in supporting the complete bolster. Said flanges 1T are each provided with openings 18 which register with holes 19 o'the side sections to receive fastening means, as rivets 20, for further securing said parts together. The central section C is also provided with center pin socket 21 and an opening 22 to admit fastening means for securing the center pin in position.

The modified construction shown in Figs. 11 to 14, inclusive, differs from the preferred construction in that the central section C of the bolster` instead of having a pair of upstanding jaws 9 embracing extensions 1 or" the bolster side sections, is provided with but a single vertical rib 23 centrally arranged upon said bolster section C and fitting between extensions 24 corresponding to the extensions 1 before indibnt spaced apart to receive saidf ib 23 en them. The rib 23 terminates in opfiositely extending connecting anges 25 as shown in Fig. 13. rlhe end flanges 26 and opposite flanges 25 are shortened to accommodate one of the bolster extensions 2-1, which lies in a plane above said flange 26 in the modification of Fig. 12.

Fig. 12 illustrates the relative positions of the engaging parts, and Fig. 14 shows the offset extensions 241 as located inthe modification orn Figs. 11 to 14, inclusive.

Shoulders 27 shownin Fig. 11 may be used with either the preferred or modified construction.

The invention is directed to the particular manner of tying the `assembled sections of the bolster together and providing a central connection for them which may be within a the center sill and connecting the lapping parts 1, 1 of the bolster sections A B directly to a central member 'of the bolster, which is shown as located between two spaced center sill members, but which, it is evident, may be combined with thek extensions A-B and form a bolster without the said interposed sill members, if desired. eIn other words, the bolster will be complete as a bolster it its side sections are carried into direct contact with the center sect-ion. In car underfra-Ines in which the center sill terminates between bolsters such an arrangement is desirable but is so evidentfrom the disclosure that it is not specifically illustrated. This member C comprises a combined bolster filler casting and center bearing plate, which is adapted to be secured between and to the webs of the spaced center sills and to the lower flanges of the bolster sections iii-B, or directly to the sections A-B if desired. Owing to the fact that the bolster center section is necessarily very strong, there is a practical advantage in the connection of the extensions 1, 1 within and to an upward extension of said casting, as best shown in Fig. 5, though it is evident i that the center bolster sections of Figs. 12, 13 and 14- may be substituted.

ln the modification illustrated in Figs. 15, 16 and 17 a short cover plate is einploycd, said cover plate being riveted or otherwise secured directly to a top or hori- 100 '/.s-ntiil flange 2, preferably formed integral with one cf the extensions 1 before referred to, the other elements of the bolster being secured as hereinbefore described.

In Fig. 18 there is shown an additional 105 modification in which the flanges 2 and 12 are directly riveted by vertically disposed rivets. l

1n Fig. 1f) the features of Figs. 15, 16, 1 7 and 18 are combined, there being shown 110 the 'cover plate 28 of Figs. 15, 16 and 17 and the wide. flange 2 of Fig. 18 and both sc- Acured by vertical rivets to wide outstanding 'I flanges 12.

Owing to the 'fact that the bolster is com- 115 posed of the principal elements comprising a. central supporting section C-a-nd two side extensions AB secured thereto, as shown, independently or the connection with center sills, it is obvious that the extensions 12p 27 of the bolster sections A-B need not be employed, except to' prevent shifting of the bolster with relation to the sills.

In assemblingand disassembling the bolster parts the presence cfcenter sills is not :Izaterial to the general design, as the parts (center and side) are then merely brought into more intimate contact if center sills are not to be interposed -between the center and side bolster sections, and-in either case License the central section C remainsthe principal supporting element for the bolster' Sas a wholej What 1VI claim is:
